COVER FOR COAL-BUNKERS.

SPECIFICATION forming part of Letters Patent No. 462,163, dated October27, 1891.

Application filed June 19 1891. Serial l\l'ox 396.8l0. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM W. REYNOLDS, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ,ofPennsylvania, have invented certain new and useful Improvements in Lidsor 00V- ers for Coal-Bunkers, &c. and I do hereby declare the followingto be a full, clear, and exact description of the invention, referencebeing had to the accompanying drawings, which form part of thisspecification.

This invention has relation to coal-bunker lids, man-hole plates,tank-covers, &c., and has for its object the provision of a novelconstruction whereby the lid or cover is capable of being readilyapplied and removed, and

lid being disconnected from the ring. Fig. 2 1s a similar view with thelid in place. Fig.

3 is a plan View of ren'noved.

A designates a flanged ring or bushing dethe ring, the cover beingsigned to be made of iron or other suitable metal, and having ahorizontal flange B, which is let into a recess in the deck or floor andsecured in place by bolts or screws 6 b. This ring is of a size andexternal form suitably adapted for use on marine vessels and is appliedto the mouth of a coal-hole of a bunker as a receptacle or holder forthe lid or cover 0. The ring, however, may be made of various sizes,proportions, and external shape, adapting it to other uses than on boardmarine vessels, such as on water-tanks, manholes of sewers or cisterns,coal-holes of streetvaults, 850. The opening through the ring isslightly tapering or flaring from its lower end toward its mouth, and inthe lower portion is fitted a circular grating D, which is a necessaryappendage when the ring is used upon coal -bunkers, as it constitutes aguard or safety appliance when the cover is removed. The upper portionor mouth of the ring is shelved or shouldered, as shown at c, for thereception and support of the circular metallic plate 0, whichconstitutes the lid or cover, and which is of greater diameter than thelower end of the ring-opening. The interior of the ring is contractedand beveled toward its lower end to allow of the grating being insertedthrough the upper end and for causing the beveled periphery of thegrating to lodge and rest inside the ring near its lower end.

When it is necessary to obtain access to the coal-bunker or otherreceptacle to which the ring is fitted, the grating may be easilyremoved by being simply lifted out of thering after the lidis removed.

For the purpose of securing the lid in place it is formed with twoL-shapedlugs or hooks cl (Z on its under side diametrically oppositeeach other, while the ring is formed with two tapering or beveledflanges or threads 6 e, separated from each other by notches ff, throughwhich the lugs or hooks (Z (Z may be passed in fitting the lid to thering. After inserting the lid it is secured by being turned around thedistance of, say, a quarter-revolution, thus causing the lugs d (Z topass under the beveled flanges e e and to impinge upon their beveledunder sides, as shown in Fig. 2 of the drawings. By thus securingthe'lid in place it is drawn into close contact with the shelved portionof the ring and the joint rendered perfectly watertight. If desired, agum gasket may be placed between the lid and the ring to insure absolutetightness of the joint, an advantage which is of special importance whenthe ring and cover are used on odorless barrels or in other situationswhere it is necessary to prevent the escape of noxious gases.

G G are flattened loops or staples secured to the upper side of the lidand having recesses H H formed in the lid underneath them for thepurpose of receiving the ends of hooks or other devices, by which thelid may be moved and lifted.
